Description
RELATED APPLICATIONS
[0001] This application claims priority to Taiwan Application
Serial Number 102144597, filed Dec. 05, 2013, which is herein
incorporated by reference.
BACKGROUND
[0002] 1. Technical Field
[0003] The present disclosure relates to a positioning frame. More
particularly, the present disclosure relates to a positioning frame
for a touch pad film.
[0004] 2. Description of Related Art
[0005] During assembly of a touch pad of a notebook computer, a
film is adhered to an upper surface of the touch pad to enhance
comfort while using the touch pad. However, when adhering the film,
the film may be shifted due to variations in physical dimensions of
a front cover or a fixing bracket as a result of these elements
having an engineering tolerance. As a result, not only the
appearance negatively being affected, but also the shifting of the
film. Such that, it interferes with the front cover. Consequently,
the touch pad may sense incorrectly or may even be unable to sense
a touch force.
[0006] Additionally, the touch pad is assembled from a back surface
of the front cover of the system (i.e., inside of a case). When the
film is shifted, the assembly worker is not aware that such
shifting has taken place. That is, the assembly worker must
determine whether the film has shifted by checking from the front
surface of the system. Ultimately, this increases labor costs.
SUMMARY
[0007] The disclosure provides a positioning frame for a touch pad.
The positioning frame includes a main frame and a positioning wall.
The positioning wall is located at a side of the main frame and is
connected to the main frame. An inner surface of the main frame and
the positioning wall define an opening. An area of the opening is
approximately the same as an area of a film to be adhered to the
touch pad. The positioning wall is configured to insert into a gap
between the touch pad and a front cover of a system body.
[0008] The present disclosure further provides a method for
adhering a film to a touch pad including the following steps: (A)
adhering a fixing bracket to a back surface of a touch pad; (B)
aligning a plurality of screw holes of the fixing bracket with a
plurality of the screw holes of a front cover of a system body,
respectively, and connecting the fixing bracket and the front cover
of the system body using screws or bolts that engage the screw
holes; (C) inserting a positioning wall of a positioning frame into
a gap between the touch pad and the front cover of the system body
from a front surface of the touch pad; (D) aligning a film with an
opening of the positioning frame, and adhering the film to the
front surface of the touch pad; and (E) removing the positioning
frame from the front surface of the touch pad.
[0009] Accordingly, through the positioning frame and method for
adhering a film to a touch pad of this disclosure, the film is
constrained on the front surface of the touch pad, so as to solve
the prior art problems caused by variations in physical dimensions
due to the tolerance of elements. In addition, the assembly worker
can see the front surface of the front cover of the system body and
the front surface of the touch pad during assembly. When the
assembly worker adheres the film inaccurately, the assembly worker
can easily notice this fact, and then proceed to rectify the
situation. In addition, the positioning frame of this disclosure
may be manufactured cheaply, and is effective in assembling the
touch pad. Finally, the positioning frame and method for adhering a
film to a touch pad and the positioning frame of this disclosure
can be used in an automatic manufacturing process, so as to
minimize labor costs.
[0010] It is to be understood that both the foregoing general
description and the following detailed description are by examples,
and are intended to provide further explanation of the disclosure
as claimed.

DETAILED DESCRIPTION
[0022] Reference will now be made in detail to the present
embodiments of the disclosure, examples of which are illustrated in
the accompanying drawings. Wherever possible, the same reference
numbers are used in the drawings and the description to refer to
the same or like parts.
[0023] In order to solve the problem of shifting of a film during
assembly of a conventional touch pad, the present disclosure
provides a positioning frame that is able to effectively solve this
problem.
[0024] FIG. 1 is a top view of a positioning frame 100 according to
an embodiment of the present disclosure. FIG. 2 is a bottom view of
the positioning frame 100 in FIG. 1. The present disclosure
provides the positioning frame 100 for a touch pad. The positioning
frame 100 includes a main frame 101 and a positioning wall 110. The
positioning wall 110 is at one side of the main frame 101 and is
connected with the main frame 101. The main frame 101 and the
positioning wall 110 are provided in a surrounding configuration to
define an opening 120. In an embodiment of the present disclosure,
the main frame 101 is rectangular. In an embodiment of the present
disclosure, the positioning wall 110 is rectangular. In an
embodiment of the present disclosure, the main frame 101 and the
positioning wall 110 are made of metal. In a preferred embodiment
of the present disclosure, a thickness W2 of the positioning wall
110 is less than 0.2 mm, thus, the positioning wall 110 must be
formed of a material that is highly malleable and structurally
strong. In an embodiment of the present disclosure, the main frame
101 has a uniform height H1. In an embodiment of the present
disclosure, the positioning wall 110 has another uniform height H2.
In an embodiment of the present disclosure, a thickness W1 of the
main frame 101 is greater than the thickness W2 of the positioning
wall 110.
[0025] FIG. 3 is a flow chart of a method for adhering a film to a
touch pad according to an embodiment of the present disclosure. The
present disclosure provides a method for adhering a film to a touch
pad that includes steps S103-S106.
[0026] In step S101, a fixing bracket is adhered to a back surface
of a touch pad (i.e., a surface that a computer user cannot
reach).
[0027] In step S102, a plurality of screw holes of the fixing
bracket are aligned respectively with a plurality of screw holes of
a back surface of a front cover of a system body, and the fixing
bracket is fixed to the back surface of the front cover using bolts
or screws that are engaged with the screw holes of the fixing
bracket and the front cover.
[0028] In step S103, a positioning wall of a positioning frame is
inserted into a gap between the touch pad and the front cover of
the system body from a front surface of the touch pad (i.e., a
surface that a computer user can reach).
[0029] In step S104, a film is aligned with an opening of the
positioning frame, and the film is adhered to the front surface of
the touch pad.
[0030] In step S105, the positioning frame is removed from the
front surface of the touch pad. If the film is adhered accurately
(e.g., the film is aligned to be adhered to the opening of the
front surface of the touch pad), a process of adhering the film to
the touch pad is finished. If the film is not adhered accurately,
then the process proceeds to step S106, in which a part of the film
is removed from the front surface of the touch pad while removing
the positioning frame. Consequently, an assembly worker can remove
the remainder of the film easily, after which the assembly worker
performs step S101 to s105 again. Such a process is repeated as
many times as necessary until the film is accurately adhered.
[0031] FIG. 4 is a bottom view of a fixing bracket 130 and a touch
pad 140 according to an embodiment of the present disclosure.
Referring to FIG. 3 and FIG. 4, in step S101, the assembly worker
aligns a fixing bracket 130 with a back surface 142 of a touch pad
140, moves the fixing bracket 130 along a direction 300, then
adheres the fixing bracket to the back surface 142 of the touch pad
140. The assembly worker may use a sticky film to adhere the fixing
bracket 130 to the touch pad 140, thereby allowing for convenient
assembly.
[0032] FIG. 5 is a bottom view of a front cover of a system body
150, the fixing bracket 130, and the touch pad 140 according to an
embodiment of the present disclosure. With reference to FIG. 3 and
FIG. 5, after the fixing bracket 130 is adhered to the back surface
142 of the touch pad 140, the assembly worker aligns a plurality of
the screw holes 132 of the fixing bracket 130 with a plurality of
the screw holes 154 of the back surface 152 of the front cover of
the system body 150, and the fixing bracket 130 is fixed to the
front cover of the system body 150 using bolts or screws that are
engaged with the screw holes of the fixing bracket 130 and the
front cover. As a result, the fixing bracket 130 and the touch pad
140 are fixed on the back surface 152 of the front cover of the
system body 150 and are aligned with an opening 156. During the
adhering process of step S101 and the fastening process of step
S102, the fixing bracket 130 and the touch pad 140 may be shifted
due to variations in physical dimensions resulting from tolerances
of different devices. However, the method for adhering a film to a
touch pad according to an embodiment of the present disclosure can
overcome the problem of shifting by the steps described in the
following paragraph.
[0033] FIG. 6 is a top view of the positioning frame 100, the front
cover of the system body 150, and the touch pad 140 according to an
embodiment of the present disclosure. After the fixing bracket 130
and the touch pad 140 are fixed on the back surface 152 of the
front cover of the system body 150, the assembly worker turns over
the front cover of the system body 150, such that the assembly
worker can see a front surface 158 of the front cover of the system
body 150 and a front surface 144 of the touch pad 140. At this
time, the assembly worker inserts the positioning wall 110 (see
FIG. 2) into a gap 160 between the front surface 144 of the touch
pad 140 and the front cover of the system body 150 by moving the
positioning frame 100 along a direction 310. The gap 160 has a
width d, and the thickness W2 of the positioning wall 110 (see FIG.
2) is less than the width d of the gap 160, such that the
positioning wall 110 can be inserted into the gap 160.
[0034] FIG. 7 is a schematic diagram before a film 170 is adhered
to the touch pad 140 according to an embodiment of the present
disclosure. Referring first to FIG. 7, after the positioning wall
110 (see FIG. 2) is inserted into the gap 160 surrounding the touch
pad 140, the assembly worker aligns a film 170 with the opening 120
of the positioning frame 100, and subsequently moves the film 170
along a direction 320 then adheres the film 170 to the front
surface 144 of the touch pad 140. The opening 120 is defined and
surrounded by an inner surface of the main frame 101 and the
positioning wall 110 (see FIG. 2). The opening 120 has an area, and
the area is approximately the same as an area of the film 170, such
that the film 170 is restricted within the opening 120.
[0035] FIG. 8 is a cross-sectional view of the film 170, the
positioning frame 100, the front cover of the system body 150, and
the touch pad 140 according to an embodiment of the present
disclosure. Because the positioning wall 110 is inserted into the
gap 160 surrounding the touch pad 140, even if the fixing bracket
130 and the touch pad 140 are shifted after assembly, the film 170
remains aligned with and adhered to the front surface 144 of the
touch pad 140 and does not become adhered to the front cover of the
system body 150. Moreover, the method for adhering a film to a
touch pad of this disclosure involves turning over the front cover
of the system body 150, such that the assembly worker can see the
front surface 158 of the front cover of the system body 150 and the
front surface 144 of the touch pad 140. Accordingly, if the
assembly worker adheres the film 170 inaccurately, the assembly
worker can be aware of this fact and can immediately proceed to
re-adhere the film 170.
[0036] FIG. 9 is a schematic diagram after the film 170 is adhered
to the touch pad 140 (see FIG. 7) according to an embodiment of the
present disclosure. FIG. 10 is a schematic diagram showing a
situation in which the film 170 is adhered inaccurately according
to an embodiment of the present disclosure. Referring first to FIG.
9, when the film 170 is adhered accurately on the front surface 144
of the touch pad 140, the process of adhering the film 170 is
finished, and the positioning frame 100 can be removed along a
direction 330. Referring to FIG. 10, if the assembly worker adheres
the film 170 to the front surface 144 of the touch pad 140 without
correctly aligning the film 170 with the opening 120 of the
positioning frame 100, the film 170 will be adhered inaccurately.
Because the area of the opening 120 of the positioning frame 100 is
approximately the same as the area of the film 170, if the film 170
is adhered inaccurately, at least a part 172 of the film 170 is
adhered to the main frame 101 or may even be adhered to the front
cover of the system body 150. At this time, the assembly worker can
be easily aware of such inaccurate adhering and can immediately
re-adhere the film 170. Even if the part 172 adhered to the main
frame 101 is extremely small and therefore not easily noticed, the
part 172 of the film 170 is removed while removing the positioning
frame 100 from the front surface 144 of the touch pad 140, such
that the assembly worker can remove the remainder of the film 170
easily. The assembly worker subsequently repeats the steps
described above until the adhering process is finished.
[0037] Accordingly, through the positioning frame and method for
adhering a film to a touch pad of this disclosure, the film is
constrained on the front surface of the touch pad, so as to solve
the prior art problems caused by variations in physical dimensions
due to the tolerance elements. In addition, the assembly worker can
see the front surface of the front cover of the system body and the
front surface of the touch pad during assembly. When the assembly
worker adheres the film inaccurately, the assembly worker can
easily notice this fact, and then proceed to immediately rectify
the situation (i.e., re-adhere the film). In addition, the
positioning frame of this disclosure may be manufactured cheaply,
and is effective in assembling the touch pad. Finally, the
positioning frame and method for adhering a film to a touch pad and
the positioning frame of this disclosure can be used in an
automatic manufacturing process, so as to minimize labor costs.
[0038] Although the present disclosure has been described in
considerable detail with reference to certain embodiments thereof,
other embodiments are possible. Therefore, the spirit and scope of
the appended claims should not be limited to the description of the
embodiments contained herein.
[0039] It will be apparent to those skilled in the art that various
modifications and variations can be made to the structure of the
present disclosure without departing from the scope or spirit of
the disclosure. In view of the foregoing, it is intended that the
present disclosure cover modifications and variations of this
disclosure provided they fall within the scope of the following
claims.
